Are the fleet keys pre-programmed or anything like that? There are a few places selling chips like this one- but the fleet keys themselves have different part numbers from GM. (2.) Do the fleet keys have the same chip as the regular keys? On the flip keys I have, I could buy a new chip and put it in if I know the one to get. (1.) Can the old keys be relearned? Or are they lost/junk? I ordered a new cut key from the dealer, and the message went away as soon as I turned the key. I tired the 10 minute Relearn, and it blanked all keys, and wouldn't relearn any of the keys. Car still started as it was fleet and PPV. Situation is I added 2 keys to my car and got a constant message 'Engine Immobilized, See Owners Manual' when the 2nd key was added.
